Hearing Professor Li Hongwei's words, Zhao Heng stood up, looked at the direction of the podium with firm eyes, and said in a very confident and infectious tone: "For a differentiated and mature cell, the realization of its nuclear totipotency is based on fusion with the cytoplasm of the egg, or in other words, the cytoplasm of the egg contains the conditions required to transform the terminally differentiated somatic cells into totipotent cells, and this transformation from somatic cells to totipotent cells is called somatic cell reprogramming. ”

"Well, well, yes, then this classmate, do you know that there are several classic schemes for somatic cell reprogramming?"

Hearing Zhao Heng's perfect answer without a trace of error, Li Hongwei was very surprised in his heart, he didn't expect that the students below this question could answer it, so he continued to ask.

"There are four classical protocols for somatic cell reprogramming, which are somatic nuclear transfer, transcription factor induction, cell fusion, and cytoplasmic incubation. Moreover, on this basis, pluripotent stem cells and various functional cells can also be obtained through cell fate regulation to achieve the effect of regeneration. ”

Zhao Heng answered Professor Li Hongwei's question very accurately, and also extended the answer to this question to the field that Professor Li Hongwei is researching.

Because Professor Li Hongwei's research field is somatic cell reprogramming, cell fate regulation and regenerative medicine application research.

"Oh? Do you also have an understanding of cell fate regulation and cell regeneration? This classmate, after class, you can stay for a while. ”

Hearing Zhao Heng's answer, the surprise in Professor Li Hongwei's heart turned into a surprise, what Zhao Heng said can be said to be a perfect hit on his cool point, because these projects are his main research.

But to be honest, although the potential and value of his research project is very large, because it is too high-end, cutting-edge and difficult, it is difficult for ordinary students, even medical practitioners, to understand his research, so he has always been in a state of being in a high place.

What he didn't expect was that in this open class, there were students who could perfectly describe his research, which made him feel more comfortable than drinking ice soda on a hot day.

So he decided that after class, he must have a good chat with this classmate, maybe it is a good seedling to inherit the mantle?

"Thank you, Professor."

Zhao Heng nodded and sat down.

The effect has been achieved, and if it continues, it will be a bit much.

Besides, now is an open class, not a discussion between the two in private, and Professor Li Hongwei also said that let him stay after class, this has basically achieved Zhao Heng's preset purpose.

As long as you can discuss with Professor Li Hongwei, then Zhao Heng's golden finger can play a role, and from Li Hongwei, the god of stem cell research, pick up the skills and experience of drop fusion, maybe you can solve the problem that Sun Xinxin's bone marrow degeneration can no longer be differentiated into neural stem cells.

Zhao Heng sat down, and the eyes of the other students in the classroom remained on him for a while.

The people sitting in these rows next to Zhao Heng stared at him from time to time, wanting to know which academy Zhao Heng was.

can be recognized by a god-level professor like Li Hongwei, and let him leave class to discuss privately, this treatment can be said to be something that few students can have.

"Senior, you're so handsome!" ”

Shu Xin, the junior school girl sitting next to Zhao Heng, saw Zhao Heng's demeanor, her smiling eyes narrowed into a slit, and she was very happy to give Zhao Heng a thumbs up.

Next, Professor Li Hongwei began to lecture, however, this class is a little different, in the original content, Professor Li Hongwei added some deep things, when talking about these contents, from time to time he looked in the direction of Zhao Heng.

Zhao Heng immediately understood that this Professor Li Hongwei was specially for him, because the other students sitting in this classroom couldn't understand these contents at all.

Attentively listening to the lecture, the time passed quickly, and the time came to half past ten in the morning, and the open class was over.

As soon as the class ended, before Zhao Heng stood up, Professor Li Hongwei's assistant Wei Jinghao had already come to Zhao Heng's side, looked at Zhao Heng with some envy, and said to him: "This classmate, the professor asked you to stay." ”

"Well, thank you, senior."

Zhao Heng nodded, and looked at the assistant teacher who looked to be in his thirties, wearing black-framed glasses, his head was already a little bald, and there were a little vicissitudes.

Is it so hard to engage in scientific research?

Seeing this teaching assistant, Zhao Heng couldn't help but think.

Zhao Heng stood up and said to the junior sister Shu Xin, "I'll go for a while." ”

"Uh-huh."

Shu Xin nodded again and again, she knew that Zhao Heng was not just here to listen to the lecture this time.

After a while, Zhao Heng came to the podium.

Professor Li Hongwei didn't speak immediately, but looked Zhao Heng up and down, confirming that he really didn't know this classmate, and then asked Zhao Heng with some doubts: "This classmate, which college are you from?" ”

The reason why I ask this is because Professor Li Hongwei also attaches great importance to cultivating younger generations, so he has talents and geniuses in several related colleges.

"Professor, I'm already working, at the Oriental Hospital."

Zhao Heng replied briefly.

"Oh? Already working? Is the work you do related to stem cell cultivation? ”

Professor Li Hongwei asked again with great interest.

In his opinion, the work done by Zhao Heng must be related to stem cell cultivation, otherwise, how could he answer his question.

"That's right, Professor, I recently took over a patient who was in a coma for a long time after a severe head injury. I would like to transplant neural stem cells to treat patients and promote awakening. But I now have a problem, that is, the patient's bone marrow is degenerating, and it is impossible to differentiate and grow neural stem cells. ”

Zhao Heng thought about it for a while, and decided to ask straight and straightforwardly.

The case of Sun Xinxin is very rare, and perhaps after saying it, Professor Li Hongwei will be interested.

"Healing head injuries with transplanted neural stem cells? Well, the idea is quite original and constructive. ”

"Is it an elderly patient? If it is senile bone marrow degeneration, I am afraid that with the current technology, it is impossible to achieve re-differentiation. ”

Hearing Zhao Heng's words, Professor Li Hongwei's eyes lit up, and he thought about it and said.

He is an absolute authority in the field of stem cells, and as soon as Zhao Heng said this, he instantly understood the situation.

Moreover, he is also very appreciative of the idea of transplanting neural stem cells to repair head injuries.

"The patient was twenty-three years old and, before the injury, was a skier."

Zhao Heng replied.

"Oh? Only twenty-three years old? However, if it is an athlete, it can be said that the training of athletes is a long-term stimulation of cell division and overdraft potential, and it is very likely that there will be degenerative changes in the bone marrow. ”

Professor Li Hongwei listened to Zhao Heng's words, thought for a while and said.

"Yes, Professor, that's what I thought too."

Zhao Heng nodded, this Professor Li Hongwei's conjecture can be said to coincide with him.
